Definitions

  • This invention relates to machinery for applying closures to containers and is more particularly concerned with improvements in a machine for automatically applying screw-on or turn-on closure caps to the tops of jars or similar containers and turning-the caps into tight sealing relation on the jar.
  • cap applying and closing machinery In the commercial processing and packaging of food products and other commodities in glass jars or similar containers with which screw threaded caps are used for closing and sealingvthe containers, various types of cap applying and closing machinery has been employed. Some of these machines place the caps on the containers and thereafter rotate the caps to turn them down to sealing position while the containers are traveling through the machine. In one such machine which has been employed, the filled containers are delivered on a straight line conveyor to a turret which carries the containers in a circular path while the caps are placed thereon and screwed down to sealing position with the capped con.- tainers being transferred from the turret to another straight line conveyor which removes them from the machine.
  • a general object of the present invention is to provide an improved cap applying machine of this type which employs a relatively small turret with a small number of cap applying heads or spindles and which is nevertheless capable of high speed operation.
  • Another object of the invention is to provide a rotary jar capping machine wherein the jars are delivered to the machine in a straight line and continue on a straight line path until they intersect the pitch diameter of the sealing turret in a chordal path with the cap being placed on the jar and turned into engagement with the screw threads before the jar has left its straight line path so as to seat the cap fully on the jar as the jar enters the circular path and before the jar is subject to sufficient centrifugal force to cause the con-tents to spill out of the jar top.
  • Another object of the invention is to provide in a rotary type jar capping machine a turret on which the jars are supported while the caps are applied and associated capping heads which include independently driven spindles for applying the cap to the jar and rotating it into seated position and for thereafter tightening the cap into sealing relation.
  • a still further object of the invention is to provide a rotary jar capping machine having cap applying and turning heads mounted on a jar supporting turret with the heads each having two independently driven spindles, one of the spindles to which the cap is initially delivered being rotated at high speed for placing the cap on the jar and rotating the same into'fully engaged position and the other spindle being operated at a relatively low speed so as to engage the cap and tighten it to a preset torque with the jar being gripped on the turret so as to hold it against rotation during the capping operations of the spindles.
  • Another object of the invention is to provide in a rotary type jar capping machine a turret having multiple stations at which the jars are supported while the caps are applied and turned into sealing relation with the turret having jar clamps at each station thereupon comprising cooperating stationary and pivotally mounted arms which are urged toward a closed position by a spring which is adjustable for various pressures and opened by a cam operating against the force of the spring for receiving or releasing the jars.
  • a further object of the invention is to provide a jar capping machine for vapor vacuum sealing which employs a system for steaming the cap and the jar with low velocity and high volume steam as the cap is positioned above the mouth of the jar and lowered to a point approximately one-sixteenth inch above the jar where a sheet of high velocity steam is directed downwards on a shallow angle and a plurality of high velocity steam jets are directed upwardly to blow steam under the cap immediately prior to the seating of the cap on the jar mouth.
